SECTION XLVIII. RICE
The United States produces only about one half of the rice that it consumes. There is no satisfactory reason for our not raising more of this staple crop, for five great states along the Gulf of Mexico are well adapted to its culture.
Fig. 221. Threshing Rice
There are two distinct kinds of rice, upland rice and lowland rice. Upland rice demands in general the same methods of culture that are required by other cereals, for example, oats or wheat. The growing of lowland rice is considerably more difficult and includes the necessity of flooding the fields with water at proper times.
A stiff, half-clay soil with some loam is best suited to this crop. The soil should have a clay subsoil to retain water and to give stiffness enough to allow the use of harvesting-machinery. Some good rice soils are so stiff that they must be flooded to soften them enough to admit of plowing. Plow deeply to give the roots ample feeding-space. Good tillage, which is too often neglected, is valuable.
Careful seed-selection is perhaps even more needed for rice than for any other crop. Consumers want kernels of the same size. Be sure that your seed is free from red rice and other weeds. Drilling is much better than broadcasting, as it secures a more even distribution of the seed.
The notion generally prevails that flooding returns to the soil the needed fertility. This may be true if the flooding-water deposits much silt, but if the water be clear it is untrue, and fertilizers or leguminous crops are needed to keep up fertility. Cowpeas replace the lost soil-elements and keep down weeds, grasses, and red rice.
Red rice is a weed close kin to rice, but the seed of one will not produce the other. Do not allow it to get mixed and sowed with your rice seed or to go to seed in your field.
